Application led May 5,

To all whom t may concern:

Be it known that I, F RED CARON, a'citize of the United States, residingaty Detroit, in the county/of IVayne and State of Michigan, haveinvented new and useful Improvements in Automatic Weather Strips, ofwhich the following is a specification.

The object of my said invention is the provision of an automatic weatherstrip for use on doors, characterized by simplicity and strength inconstruction and reliability in operation.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawing, forming part of this specification Figures1 and 2 are views showing my improvement as properly arranged relativeto a door, Figure 1 showing the working parts in normal or idlepositions, and Figure 2 showing the parts in the positions they assumewhen the door is closed.

Figure 3 is a vertical section taken through the weather strip in theline 3 3 of Figure 2. y

Figures 4 and 5 are detail views'hereinafter explicitly referred to.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

My novel weather strip is carried in the manner illustrated by the lowerend portion of the door 1, and among other elements the weather stripcomprises a metallic body plate 2. The weather strip also comprises anauxiliary plate 4; spaced from the body plate 2 and having a flange 3fixed with respect thereto.

Carried by the metallic body plate 2 and interposed between the saidplate 2 and the auxiliary plate 4, Figure 3, are the working parts ofthe weather strip, the said working mechanism including a thrust bar 6,a pad 7 carried thereby, levers 8, and a retractile spring 9. The thrustbar 6 is formed of a single piece of sheet metal bent transversely, andthe pad 7 is arranged and secured by pins 5 or other means between theside portions of the said bar 6. In the upper edge or bight portion ofthe bar 6 are provided openings 10, Figures 3 and 4, and through theseopenings 10 extend anchors 11 on bodies 11X which carry aperturedbracket plates 12. The levers 8 are provided with eyes 13 and are alsoprovided with lateral studs 14 by 1922. serial no. 558,671.

which they are pivotally connected to the bracket plates 12 asillustrated; Said levers 8 are fulcrumed at 15` to the body plate 2, andthe spring 9 is interposed between and connected to the eye 13 of onelever 8 and the stud 14 connecting the other lever 8 to the respectiveplate 12; it being understood in this connection that the studs 14 areheaded as shown in Figures 1 to 4 so that the spring 9 may be reversedwhen the door is hinged at the right hand side instead of at the lefthand side or edge as appears in Fig ure 2. The retractilespring 9 isarranged in parallelism to the body plate 2, and serves to yieldinglyretain the bar 6 in and to re turn said bar 6 to the position shown inFig ure 1. When, however, the door is closed and the bar 6 is thrusttoward the right, the spring 9 will be put under tension. From this itwill be readily understood that while when the door is closed the bar 6is thrust endwise toward the right, and the pad 7 is crowded against thefloor or against the door sill, yet when the door is opened, the spring9 will operate to promptly raise the-bar 6 and the pad 7 so as toprevent the latter from interfering in any measure with the free openingof the door.

It will be manifest from the foregoing that my novel strip is simple andinexpensive in construction, is susceptible of ready application to adoor, and is adapted when properly applied to a door to reliably operateand to withstand for an indefinite period of time the rough usage towhich weather strips of doors are ordinarily subjected.

For the sake of prolonging its usefulness and assuring proper operationthe thrust bar 6 is provided at its forward end and adjacent to itsupper edge with a bumper portion 15', preferably of metal and designedto sustain the wear when the bar 6 is engaged for the rearward movementthereof.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a full, clear and exactunderstanding of the said embodiment. I do not desire, however, to beunderstood as confining myself to the said specific construction andrelative arrangement of parts inasmuch as in the future practice of theinvention various changes and modifications may be made such as fallwithin the scope of my invention as defined in my appended claims.

Having ldescribed my invention, what 1 claim and desire tosecure byLetters-Patent,

i a body, levers carried by said body and havingupperand lower arms, .avthrust bar of inverted- U-shape in cross-'section having openings inits top, a pad carried by said thrust bar, brackets secured on thethrust bar by anchors extending through said openings, pins. extendingthrough and connecting the lower arms of the levers and the brackets,said pins having heads, and a retraetile spring connected to the upperendV of one lever and Connected at its oppositeend to the headed pin orstud pivotally connecting the lower arm ofthe other-leverv to a'bracket.

In testimony whereof I aHiX my signature.

i FRED CARON.
